recovery deleted CF data

Firstly : we bought a card-reader (30 euro's/ dollars? ). Then rudi cautiously tried some things out with the 32 mb card that came with the camera. Then he started to phone around with some workmates about further info. It seemed they had a program he could use to try to undelete the files.
Well he's been trying a lot of things to assure that nothing would happen to the 256 Mb card first. Eventually he used ONTRACK Easy Recovery Professional Edition 5.1 to undelete the files. It worked allright!! So thanks you all for the extra info.

My CF cards are formatted FAT16 and 1 kb /cluster by the camera Canon G3.
I was afraid that Canon would use a slightly different encryption or something but even Raw files and movies did ok.
They are readily readable in the card-reader and files can be put from the directory to the camera and be readable there too.

I forgot to mention perhaps THE MOST IMPORTANT thing : after deleting and as soon as you realise what's happened : DON'T use the CF or drive to put something else on it, not even the recovery program! Use another drive, another partition or some recovery programs run from floppy. This is really the most important thing because if you put something back on the drive or CF card it possibly makes the data or part of the data unreadable.
